Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] In order to solve the problem of unilateral assembly, the technical solution adopted by the present invention is: the ordinary nut is changed to be composed of two smooth half rings, and the outer contour of the half rings can be polygonal or circular. The half-ring nuts are connected by a short shaft. The two half-rings can be opened into an "S" shape but will not be separated. On one side of the two half-rings, there is a groove with the same contour as the protruding disc at one end of the screw, which is used for the bolt rod body. position. There are threads on the body of the screw rod, one end has a protruding disk with a diameter slightly larger than the rod body, and the other end has a section of the rod body at the end where the diameter becomes smaller to become a rod end connector, so as to facilitate the connection between the insta...

Abstract

The present invention relates to a one-way bolt and nut fastener and its mounting method, belonging to the field of mechanical assembly technology. It is characterized by that the described screw bolt and nut are specially-designed, said nut is formed from two halt-rings, between said two half-rings a short shaft is connected, said two half-rings can be combined together and formed into a 'S' form, also can be closed into a ring form. One end of said screw bolt has a projected disk for positioning nut, and one side of said nut has a recessed groove identical to the projected disk profile, said recessed groove can be used for positioning said screw bolt body. Said invention also provides its special mounting tool, and also provides its concrete mounting method and steps.

Description

technical field [0001] The invention relates to a bolt fastener capable of unidirectional fastening from one side and an assembly method thereof, belonging to the technical field of mechanical assembly. Background technique [0002] Common bolt fasteners generally consist of nuts and screws. When installing, you need to clamp the nut or nut on one side, and tighten the nut or nut with a wrench from the other side. In general, the installer has access to both sides of the object being fastened. However, for special applications, such as closed tubular structures or structures where one end is not easily accessible, the use of ordinary bolts is greatly limited. Contents of the invention [0003] In order to overcome the disadvantage that existing bolts cannot be fastened from one side, the present invention provides a bolt fastener capable of one-way fastening from one side and an assembly method thereof. The performance of the fastener is similar to that of the existing ...
